mately 55 litres.Unscrewing the tank cap
– Lift the lid.
– Grip the cap and then insert the key into the lock and rotate 180°
to the left.
– Unscrew the cap, turning it anti-clockwise.
Closing the tank cap
– Screw the tank cap to the right, until the point of feeling a “click”. – Turn the key in the lock, without unscrewing the cap, clockwise
through 180°.
– Remove the key and close the flap until it clicks into place. The tank cap is secured with an anti-loss attachment
The tank flap is at the rear of the vehicle on the right.
If the automatic filler nozzle is operated correctly, it will switch itself off as
soon as the tank is “full”. Never attempt to fill beyond this point, as this will
fill the expansion chamber. Fuel may leak out if ambient conditions are warm.
The correct fuel grade for your vehicle is given on a sticker on the inside of the
fuel tank flap. Where further notes on fuel can be found.
WARNING
•Fuel is highly inflammable and can cause serious burns and other inju-
ries.
−Never smoke or use any naked flame when filling the fuel tank of the
vehicle, or a spare fuel canister, with fuel. This is an explosion hazard.
− Follow legal requirements for the use of spare fuel canisters.
− For safety reasons we do not recommend carrying a spare fuel
canister in the vehicle. The canister could be damaged in an accident
and leak.•If, in exceptional circumstances, you have to carry a spare fuel canister,
please observe the following points:
−Never fill the spare fuel canister inside the vehicle or on it. An elec-
trostatic charge could build up during filling, causing the fuel fumes to
ignite. This may be fatally explosive. Always place the canister on the
ground to fill it.

WARNING
All work on the engine or in the engine compartment, e.g. checking and
refilling fluids, involves the danger of injury and scalding as well as the risk
of accident or fire.•Never open the bonnet if you see steam, smoke or coolant escaping
from the engine compartment. Otherwise, there is a risk of sustaining
burns. Wait until no more steam or coolant is emitted, then allow the
engine to cool before carefully opening the bonnet.•Switch off the engine and remove the key from the ignition.•Apply the handbrake and move the gear stick to neutral or selector
lever to position P.•Keep children away from the vehicle.•Never touch hot engine parts. There is a risk of burns.•Never spill liquids on a hot engine or on a hot exhaust gas system. This
is a fire hazard.•Avoid causing short-circuits in the electrical system, particularly at the
points where the jump leads are attached ⇒ page 276. The battery could
explode.•Never touch the radiator fan. It is temperature controlled and could
start automatically, even when the engine has been switched off and the
key removed from the ignition!•Do not unscrew the cap on the expansion tank when the engine is hot.
If the coolant is hot, the cooling system will be pressurised!•Protect face, hands and arms by covering the cap with a large, thick
cloth to protect against escaping coolant and steam.•Always make sure you have not left any objects, such as cleaning cloths
and tools, in the engine compartment.•If you have to work underneath the vehicle, you must use suitable
stands additionally to support the vehicle, there is a risk of accident!. A
hydraulic jack is insufficient for securing the vehicle and there is a risk of
injury.
•If any work has to be performed when the engine is started or with the
engine running, there is an additional, potentially fatal, safety risk from the
rotating parts, such as the drive belts, alternator, radiator fan, etc., and
from the high-voltage ignition system. You should also observe the
following points:
−Never touch the electrical wiring of the ignition system.
− Ensure that jewellery, loose clothing and long hair do not get
trapped in rotating engine parts. Danger of death. Before starting any
work remove jewellery, tie back and cover hair, and wear tight-fitting
clothes.
− Always think carefully about pressing the accelerator if a gear is
engaged in either an automatic or manual gearbox. The vehicle could
move, even if the handbrake is applied. Danger of death.•If work has to be carried out on the fuel system or on electrical compo-
nents, you must observe the following safety notes in addition to the above
warnings:
−Always disconnect the battery. The vehicle must be unlocked when
this is done, otherwise the alarm will be triggered.
− Do not smoke.
− Never work near naked flames.
− Always have a fire extinguisher on hand.Caution
When changing or topping up service fluids, make absolutely certain that you
fill the fluids into the correct reservoirs. Failure to observe this point will result
in serious malfunctions and engine damage!

Engine oilEngine oil specifications
The engine oil used must conf orm with exact specifications.Specifications
The engine comes with a special, high quality, multi grade oil that can be
used in all seasons of the year except for those regions affected by extreme
cold.
As the use of good quality oil is necessary for the correct operation and long
service life of the engine, when it becomes necessary to replenish or change
the oil, always use an oil that complies to the VW standards.
If it is not possible to find oil conforming to the VW standards then oil
conforming to the ACEA or API standards with an appropriate viscosity at
atmospheric temperature should be used instead. The use of this type of oil
may have some repercussions on the performance of the engine for example,
long starting time, increased consumption and a higher emission level.
If a top up is required then different oils may be mixed as long as they all
conform to the VW standards.
The specifications (VW standards) set out in the following page should
appear on the container of the service oil; the container will display together
the different standards for petrol and diesel engines, the oil can be used for
both types of engines.

Wheels and tyres249
Safety First
Operating instructions
Practical tips
Technical Data
Wheel bolts
Wheel bolts must be tightened to the correct torque.The design of wheel bolts is matched to the rims. If different wheel rims are
fitted, the correct wheel bolts with the right length and correctly shaped bolt
heads must be used. This ensures that wheels are fitted securely and that the
brake system functions correctly.
In certain circumstances, you may not use wheel bolts from a different car -
even if it is the same model ⇒ page 218.
After the wheels have been changed, the tightening torque of the wheel bolts
should be checked as soon as possible with a torque wrench ⇒. The tight-
ening torque for steel and alloy wheels is 120 Nm.
WARNING
If the wheel bolts are not tightened correctly, the wheel could become
loose while driving. Risk of accident.•The wheel bolts must be clean and turn easily. Never apply grease or oil
to them.•Use only wheel bolts which belong to the wheel.•If the torque of the wheel bolts is too low, they could loosen whilst the
vehicle is in motion. Risk of accident! If the tightening torque is too high,
the wheel bolts and threads can be damaged.Caution
The prescribed torque for wheel bolts for steel and alloy wheels is 120 Nm.
Winter tyres
Winter tyres will improve the vehicles handling on snow and
ice.In winter conditions winter tyres will considerably improve the vehicles
handling. The design of summer tyres (width, rubber compound, tread
pattern) gives less grip on ice and snow.
Winter tyres must be inflated to a pressure 0.2 bar higher than the pressures
specified for summer tyres (see sticker on tank flap).
Winter tyres must be fitted on all four wheels.
Information on permitted winter tyre sizes can be found in the vehicle's regis-
tration documents. Use only radial winter tyres. All tyre sizes listed in the
vehicle documentation also apply to winter tyres.
Winter tyres lose their effectiveness when the tread is worn down to a depth
of 4 mm.
The speed rating code ⇒ page 248, “New tyres and wheels” determines the
following speed limits for winter tyres: ⇒
Q max. 160 km/h
S max. 180 km/h
T max. 190 km/h
H max. 210 km/h
In some countries, vehicles which can exceed the speed rating of the fitted
tyre must have an appropriate sticker in the driver's field of view. These
stickers are available from your Authorised Service Centre. The legal require-
ments of each country must be followed.
Do not have winter tyres fitted for unnecessarily long periods. Vehicles with
summer tyres handle better when the roads are free of snow and ice.
If you have a flat tyre, please refer to the notes on the spare wheel
⇒ page 248, “New tyres and wheels”.
